It has 2mb chip + 6 mb fas memory

There's no way an A3k could have 6 MB (fast) onboard. You can use 1-4 banks of memory with either 1 MB (4x256Kb chips) or 4 MB (4x1024Kb chips) each - no mixing possible - you could have 1, 2, 3, 4, 8, 12 or 16 Meg fast RAM, but not 6 (FastROM uses 512 KB of RAM, but certainly not 2 Megs).

Showconfig tells you where the RAM is at. Chip is $2000-$1FFFFF, Fast grows from $7FFFFFF downwards (to $7400000 if you've got 12 Megs). :-)

@all
Anyone with spare 4 MB static column to sell? Or trade for 4 MB fast page?
